ABSTRACT

HCoV-OC43 is one of the mildly pathogenic coronaviruses with high infection rates in common population. Here, 43 HCoV-OC43 related cases with pneumonia were reported, corresponding genomes of HCoV-OC43 were obtained. Phylogenetic analyses based on complete genome, orf1ab and spike genes revealed that two novel genotypes of HCoV-OC43 have emerged in China. Obvious recombinant events also can be detected in the analysis of the evolutionary dynamics of novel HCoV-OC43 genotypes. Estimated divergence time analysis indicated that the two novel genotypes had apparently independent evolutionary routes. Efforts should be conducted for further investigation of genomic diversity and evolution analysis of mildly pathogenic coronaviruses.

ABSTRACT

OBJECTIVE: To evaluate the features of preoperative preparation and postoperative outcomes in patients with lung cancer and previous COVID-19 pneumonia. MATERIAL AND METHODS: There were 7 patients with non-small cell lung cancer and previous bilateral viral pneumonia between June 2020 and January 2021. In 3 cases, lung cancer was detected in a hospital for COVID-19 patients. Four patients had persistent structural changes in X-ray images. After appropriate preparation, all patients underwent total resection. RESULTS: At admission, all patients had severe physical and functional exhaustion associated with prolonged hypoxia and adynamia that required preoperative rehabilitation. Considering high risk of thromboembolic complications, we administered anticoagulation throughout the entire perioperative period and after discharge. Surgical treatment included anatomical resection (extended lobectomy). Postoperative complications occurred in 2 cases and were associated with prolonged air discharge through the pleural drainage tube. CONCLUSION: As we study the consequences of the new coronavirus infection COVID-19, it becomes obvious that a new category of patients requiring specific diagnosis and treatment has emerged.

ABSTRACT

There is growing evidence that COVID-19 not only affects the lungs but beyond that the endothelial system. Recent studies showed that this can lead to microcirculatory impairments and in consequence to functional disorders of all inner organs. The combination of endothelial dysfunction with a generalized inflammatory state and complement elements may together contribute to the overall pro-coagulative state described in COVID-19 patients leading to venular as well as to arteriolar occlusions.
